Problem 17

Number letter counts

If the numbers 1 to 5 are written out in words: one, two, three, four, five, then there are 3 + 3 + 5 + 4 + 4 = 19 letters used in total.

If all the numbers from 1 to 1000 (one thousand) inclusive were written out in words, how many letters would be used?

**NOTE:** Do not count spaces or hyphens. For
example, 342 (three hundred and forty-two) contains 23 letters and 115
(one hundred and fifteen) contains 20 letters. The use of "and" when
writing out numbers is in compliance with British usage.
